C70 Roof problem
Hi. I have a C70, 2006 metal roof version. There's a fault on the roof.
It doesn't open fully. It gets as far as popping the roof into the boot but doesn't close the boot. I can finish the cycle by using the limp home mode. On the close cycle, it closes nearly all the way, and then stops. Again, the limp home mode closes it eventually. I'm hoping it might be something fairly simple, like adding more hydraulic fluid - probably a bit optimistic. :) The battery is a bit low, as we haven't been using the car much. But, I charged the battery overnight, and the roof is still misbehaving. I have had a bit of a leak into the nearside rear footwell. Enough water to cause some sloshing. I'll deal with that separately, but I thought I'd mention it in case it's relevant. |

The roof problem is probably a broken wire in the roof loom on the left rear where it bends as the roof goes up and down .. It will need professional diagnostics to see which sensor is causing it .. In 90% of the cases its NOT the sensor but the wiring .. |

I'll also visually check the wiring loom. Is that by the left boot hinge? |

Pull back the trim in the right hand side of the boot to gain access to the roof control module. Pull the multipin connector and examine all the pins. Clean throughly, then reassemble. Water ingress or even high humidity is a known issue causing these pins to corrode.
My 2011 C70 Solstice was just 4 years old when I bought it as a Volvo Selekt car. After just a couple of months of ownership, the roof started to play all sorts of tricks, finally refusing to open at all. My local dealer (not the one I bought it from) went straight to the control module, cleaned up the pins on the connector which had gone green and bingo - everything was well again. Worth a look as its very quick and simple. John |

No, you definitely don't need to cut the trim.

Resuts?
Didi that work? Or, did you have to go to the dealer?

Sorry, I meant to come back sooner and report.
The problem seems to have resolved itself since I took a number of steps. I found that there was some water in the boot. I eventually managed to clear both the drainage channels. I also cleared out any dirt round the bottom of the rear window and thoroughly cleaned the seal round the boot. So far as I can see, no more water has been getting in. The foam around the roof hydraulic pump was saturated with water. I took that off and took it in the house to dry. I also removed the boot liner, as far as possible and took that in the house. That coincided with a hot dry spell of weather, so I left the boot open for a while to dry out. I also found that the rear nearside footwell was very wet. There may be a roof leak as well as a boot leak, or can water get into the footwell from the boot? The footwell is also dry since the boot has dried up. Hope this helps. The car is coming up to 15 years old, and it still drives well. |
